Today I received an answer to my support ticket regarding support of fansites and patch information of 4game ragnarok online (new euRO).
Sadly they can't share details so I won't be able to add a changelog for them at the moment.
Thank you for the interest to Ragnarok Online.
Unfortunately, we will not be able to share more detailed information than the game client has (basic descriptions of skill items, etc.). I hope for your understanding.
